Abstract When processing the fixed deformation data of Shanxi province,it is found that the abnomal phenomenon appeared before Wenchuan Ms8.0 earthquake, which are as follows. 1)3 months before the earthquake occurred, the tilt tidal factor γ value of quartz horizontal pendulum and water tube teltmeter in Qianxian, Xi’an, Baoji and Hanzhong stations was evidently increasing; 2)1 day before the earthquake occurred, The distortion phenomenon appeared in the NS direction data of water tube tiltmeter at Qianxian and Xi’an stations.
Key words :
ground tilt
tidal facior
distortion
abnormal phenomenon
Wenchuan earthquake
